Human VEGF (Active)

The Human VEGF (Active) protein from Antibodies.com is a biologically active recombinant form of human Vascular Endothelial Growth Factor-A (VEGF-A), supplied as a 100U lyophilized preparation for basic and translational research applications. VEGF-A is a disulfide-linked homodimeric glycoprotein of approximately 42 kDa that plays a central role in angiogenesis, vasculogenesis, and vascular permeability, making it a key reagent for studies in oncology, wound healing, cardiovascular biology, and retinal disease.

This lyophilized active protein is intended for research use only and is commonly used to stimulate endothelial cell proliferation, migration, and tube formation assays in cell culture, as well as serving as a standard or positive control in western blot, immunohistochemistry, and in vitro angiogenesis models. Upon receipt, the product should be stored at -20°C, preferably in single-use aliquots to limit freeze-thaw cycles and preserve bioactivity; reconstitution is typically performed in sterile deionized water or appropriate assay buffer before dilution into working concentrations. The unconjugated format allows direct use in functional assays or flexible coupling to detection reagents as required by the experimental design.
